Question 1

Does interaction framework also called conceptual design

Answer 1

Yes

Question 2

What is interaction framework

Answer 2

Framework phase defines the design structure and flow of computer based product.

Question 3

What are 6 factors defining the interaction framework

Answer 3

1- Defining form factor and input method
2- Defining views
3- Defining functional and data elements
4- Determining functional groups and hierarchy
5- Sketching the interaction framework
6- Constructing key path scenarios

Question 4

Does design a linear process or iterative process

Answer 4

Iterative and incremental

Question 5

Do we go from abstract to concrete in interaction framework

Answer 5

Yes

Question 6

What happens in step 1 of interaction framework (Defining form factor and input method)

Answer 6

• We define the basic posture of application

- Some perspectives (interaction paradigm, use of metaphor)

Question 7

What happens in step 2 of interaction framework (Defining views)

Answer 7

• Define different views in screen

Question 8

What happens in step 3 of interaction framework (Defining functional and data elements)

Answer 8

• Define panes, frames and other containers on screen
• Grouping of on-screen and physical controls
• Individual on-screen controls
• Individual buttons, knobs and other physical affordance on a device
• Data objects (icons, listed items, images, graphs) and associated attributes
• Functional elements are also to consider

Question 9

What happens in step 4 of interaction framework (Determining functional groups and hierarchy)

Answer 9

Once we have top elements now we can segregate them into groups and hierarchy (e.g. menus in ms word)

Question 10

What happens in step 5 of interaction framework (Sketching the interaction framework)

Answer 10

Sketch the design (e.g. balasmiq)

Question 11

What happens in step 6 of interaction framework (Constructing key path scenarios)

Answer 11

• Define key pass scenarios
• Result from exploring details
• Make use of prototyping technique

Question 12

What is key pass scenarios

Answer 12

What kind of tasks user wants to perform in detail

Question 13

On what 2 scenario basis we can develop prototype

Answer 13

1. Key pass scenarios

2. Context scenarios

Question 14

What is prototype

Answer 14

Prototype is a representation of a system that is going to develop

Question 15

What are 2 techniques of prototype

Answer 15

1. Low fidelity

2. High fidelity

Question 16

What about low fidelity prototyping

Answer 16

• story boarding

- sketching

Question 17

What is story boarding

Answer 17

Story boarding is a technique used in movies and films

Question 18

What about high fidelity prototyping

Answer 18

• Consists of adding more details to the interface

- Consists of visual design

Question 19

What are advantages of low fidelity prototype

Answer 19

• Low development cost
• Evaluate multiple design concepts
• Useful communication device
• Address screen layout issues
• Useful for identifying market requirements

Question 20

What are disadvantages of low fidelity prototype

Answer 20

• Facilitator-driven
• Limited error checking
• Proof detailed specification to code to
• Limited usefulness for usability tests.
• Limited utility after requirements established
• Navigational and flow limitations.

Question 21

What are advantages of high fidelity prototype

Answer 21

• Complete functionality
• User-driven
• Use for exploration and test
• Look and feel for final product
• Marketing and sales tool

Question 22

What are disadvantages of high fidelity prototype

Answer 22

• More expensive to develop
• Time-consuming to create
• Inefficient for proof-of-concept designs
• Not effective for requirements gathering

Question 23

What happened in refinement phase

Answer 23

• High fidelity prototyping techniques

- Look and feel is defined
